IMPROVEMENT IN WIRE-TWISTERS.

Specification forming part of Letters Patent No. 218,323, dated August5, 1879; application filed April 5, 1879.

To all whom it may concern:

Be it known that I, ISHAM SEDGWICK, of Trenton, in the county ofRandolph and State of Indiana, have invented certain new and usefulImprovements in Machines for Making Twisted-Wire Fabrics; and I dohereby de clare that the following is afull, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specification, in which- Figure l is afront elevation of a machine embodying the improvements in my invention.Fig. 2 is a side elevation of the same. Fig. 3 is a vertical centralsection, Fig. 4 is a horizontal section, Fig. 5 is a sectional detailview, Fig. 6 is a perspective detail View, Fig. 7 is a sectional detailview, Fig. 8 is a detail view, and Fig. 9 is a sectional detail view, ofthe invention.

Identical parts in the drawings are designated and referred to by thesame letters.

My invention relates to machines for making twisted-wire fabrics; and itconsists in the improvements in the construction of the machine,hereinafter fully described, and par-= ticularly pointed out in theclaims.

Referring to the drawings, A designates the wheel for operating themechanism, which is preferably driven by the pinion A upon the shaft a,which latter should be provided with a fly-wheel to impart a regularmotion to the mechanism. A A A, and A are lugs, preferably composed ofanti-friction sleeves on studs set in the face of the driving-wheel A,and located, as shown in the drawings, to engage with the cams B, B Band B upon the left of the center of the plate B and the cams B B B andB upon the right of the center of the plate 13, in such a manner as totrans- Init from the rotary motion of the driving wheel A to the plate13 a compound intermitting reciprocating motion, described more fully asfollows, viz.: When the plate B is in its extreme left-hand position, asshown in Fig. 5, the lug A engages the cam B, and the driving-wheel A,continuing to revolve in the direction indicated by the arrow, causesthe plate B to be moved to the right a distance made positive anduniform by the fixed inclination of the cams. The plate B then remainsat rest in that position until moved in a similar manner by the lug Aengaging the cam B The plate B is again at rest until moved in the samedirection by the action of the lug A and cam B when it is again at restuntil it is a fourth time moved to the right, thus providing a compoundintermittent motion of this plate B to the right. In like manner, thesame lugs A, A A and A consecutively engage the cams B B B and B andcause an intermittent motion, or, rather, a series of intermittentmotions, which returns the plate B to its original position at the left,as described, thus producing a reciprocating motion by means of a seriesof intermittent motions in each direction. The plate B is rigidlyconnected to the plate B B by means of the stud b b.

C (see Fig. 2) is a companion plate of B B and is placed in operativeconnection with it by means of the rack b on B B the pinion b and therack c on plate 0.

D are spools for storing and carrying wire intended to enter into theconstruction of the fabric. These spools are supported and carried inproper places by spool-carriers D I) D D, which are provided with theflanges d and the drivers d.

E are flanged plates, which are attached to the plates B, B and O, andso constructed and arranged that the spool-carrier D will slide freelybetween them longitudinally, and be rigidly held in position vertically.

The plate B B being in the left position, as before described, and therack c of the plate 0 being engaged with the pinion I), so as to placethe spool-carrier D, situated in channel 6 (see Fig. 4) of plate B Bopposite to the channel 0 of plate 0 at a time in the motion of themachine when the drivingrack F, traveling upon the ways F and operatedby the pinions f f f, shaft f f f, crank f and connecting-rod f engagesthe driver (1, and forces D into the channel 0 of plate 0, plate 13 B ismoved, by one of the cams and lugs before described, to the right, andplate G, by the pinion and racks, is moved to the left, as described,which reverse intermittent motions are sufficient to place channel 0 ofplate B B opposite channel 0 of plate 0, when the driving-rack F engagesthe drivers (1, and forces the spool-carrier 1) into channel 0 of theplate B B.

By a similar motion of the driving-wheel the carrier D is placed in thethird or 0 channel of the plate B B. The motions of this carrier Dduring these motions are, first, a longitudinal motion from channel a ofplate l I to channel 0 of plate C; second, thence to the left, or alatitudinal motion to the left; third, thence longitudinally from c tochannel r,- fourth, thence by the motion of the plate I) Blongitudinally to the right, thus completing the transfer of around arectangular path to its place of starting; fifth, thence againlongitudinally from c to 0 sixtlnthence again latitudinally to the left;seventh, thence from c to 0 eighth, thence again a latitudinal mo tionto the right, completing the second revolution to the left of I); ninth,thence from c to c; tenth, thence latitudinally to the right; eleventh,thence from c to c; twelfth, thence latitudinally to the left;thirteenth, thence from 0 into 0 fourteenth, thence to the right;fifteenth, thence from c to e thence left to the original position, thuscompleting two revolutions of I) to the right.

The outer wirecarriers, I) D I), pass through motions identical withthose described of the carrier 1), which, in the aggregate, consist oftwo revolutions or circuits to the left by four right-angled motions foreach revolution or circuit, and two revolutions or circuits to the rightby four right-angled motions to each revolution or circuit.

G G are stationary spools on a frame for storing the edge-wires. G (l' Gare spools for storing a part of the wire for forming the meshes of thefabric. There are (see Figs. 3 and 5) stationary pulleys g on the shaftg, and g are movable pulleys on the same shaft. These pulleys are forguiding the wires and shifting the position of the wires on the movablepulleys, to better enable the wires attached to and extending from thespools on the spoolcarricrs to be carried around the wires extendingupward from the pulleys g and g These movable pulleys g are shifted bymeans of the rack G and crank and connecting-rod g, operated by theshaft G. the movable pulleys to the right simultaneously with the firstlongitudinal motion of the carrier D, so as to lessen the longitudinalmotion required to pass the carriers D, &c., around the wires G, andreturns them to their original position on the ninth movement beforedescribed.

H is a plate extending from h to h, which are transverse beams of theframe. This plate is provided with a series of circular holes, h", whichare adapted to receive the twisters H H, shouldered, as shown in Fig. 9.These holes are connected by means of the slots k H is the top plate orcompanion plate of H, and is provided with slots h h and circular holesh. The plate 11 is held at a distance above the plate H by means of theinterposed This rack shifts strips or webs h. The holes h-' and slots hare located above those of the plate II. The webs h form the slot orspace it between H and H II" are the disks which twist the wire intomeshes, provided with the open centers or eyes If, the notches h intheir peripheries, the teeth h", and the hubs h" H is a rack playing inthe space It, engaging all of the disks H and revolving them, first, tworevolutions to the left, and then two to the right, by the movement ofthe rack to the right and left, caused by the pinion b shaft 11 andpinion b simultaneously with the right and left movement of the plate BB.

K is a sliding plate, provided with the holes 7:, inclined slots It, andright-angled slots k Ir are ways, which are attached to the plate H toserve as guides for the sliding plate K. Slots k are for the edge-wires.These righta-ugled slots k are immediately above the central openings oreyes of the twisting-disks, and they are located to allow the slidingplate K to move horizontally when the side or edge wires of the fenceare passing through the eyes of the twisting-disks.

In case tension-wires running through the fence, but not deflected, beintroduced,they would also pass through the eyes of the twistingdisksand play in these slots k.

L is a shaft transmitting motion from the driving-wheel A by means ofthe pinionsfff f shaft f f and pinion l, which connects the crank l ofthe pinion M and ear r of the lever It.

The connecting-rod l is slotted, as shown at 1 in such a manner that thecrank I operates it but one-half of a sweep.

M is a spur-wheel, carrying the wrist-pin m, driven by the pinion M'.

N is a bifurcated rod, provided with book n on one arm, and the face aon the other arm, of the bifurcated end or arm of the rod. Its long armn engages the arm 0 of the rocking shaft 0. There are longer arms, 0attached to the .shaft 0, which are connected with the sliding plate Kby rods 0 I is a crank on shaft G which serves as the fulcrum of thebifurcated arm or lever N.

R, Figs. 1 and 2, is the feed-lever, which has an intermittent motiongiven it by means of the slot 1 in the connectiug-rod I. This feed-leverhas a slot, 1, a pawl, 1' and an adjustable ear, 1, by means of whichthe feed motion given to the feed-rollers may be regulated at will.

S is the feed-roller, and T and U are cooperating fecd-rollers, whichmay be forced upon the roller S in any suitable manner. These rollers Tand U also serve the purpose of binding the fabric preparatory torolling it up for packing.

An additional rack, similar to rack B, may be placed,in connection withthe toothed disks or twisters II. on one side of them, opposite to therack H, and operated by the same pinion, b, that operates H Theadvantage of such an arrangement of parts is, that these two racks,operating in reverse directions upon opposite sides of the twisters Hprovide an easier and more positive motion of the parts of the machine.

The operation of the machine is as follows: The two wires G G are theoutside or edge wires of the fabric, as shown. These wires pass fromtheir spools of the same letter to the stationary pulleys g g on theshaft g, and from there extend upward through the eyes of thetwisting-disks vertically above the pulleys g g, and from there theypass between the draw-feed rollers S T U.

The three wires G G G pass from their spools of the same letter over themovable pulleys g on the shaft g and from there vertically upwardthrough the notches upon the right-hand side of alternate ones of theseries of twisting-disks H and upward to the feedrollers.

The wires 1) I) D from the supply-spools, located upon the carriers ofthe same letters, are passed through the notches upon the op posite orleft sides of the same twisting-disks, and then upward under thefeed-rollers.

The wire I) is passed through the left-hand notch of the twisting-disk,that has the lefthand edge-wire through its center, and then upwardbetween the feed-rollers. This position of the wires is again reached ateach alternate twisting in the mesh formation.

The movements of the spoolcarriers, hereinbefore described, pass thewires D D D twice around to the left, and around their respective Gwires, as shown in Fig. 1, and also,passes the D wire twice around the Gor edge wire, forming the double twists 1: m at; and then as thecarriers are moved to the right, as hereinbefore described, the D wireis passed twice to the right around the right-hand G wire, and the D D Dwires are each at the same time and in like manner passed around theirrespective G wires, forming the double twistsoc m .02 Simultaneouslywith these several motions of the spoolcarriers and their wires thetwisting-disks have formed the two twistings 00 and afi-the first, w,twisted to the left, and the second, 00 to the right-and the mot-ions ofthe wires which I have described have prevented any twisting or meshformation below the plate H.

The holding of the wires in the twistingdisks, and their transfer at theproper time from one disk to another, are accomplished in the followingmanner, reference being had to Figs. 7, 8, and 9 The wires are passedthrough the notches h of the twisting-disks. These twisting-disks areconstructed with an eye, h", through which the edge-wires of the fabricare passed. The twisting-notches h in the peripheries of the disks,where the wires which form the fabric are placed, the teeth k forrevolving the disks by the rack 11, the hub k of the disk H formed torest in the holes h, and the plate H hold these disks in position,

while the edges of the holes k in plate H retain the wires in thenotches of the disks while the twisting is being done.

The machine is so constructed and set up that as the plates B, B and Oare at rest, the notches h" of the twisters are in line with the slots kof the plate H, and for each movement of the plates B, B, and O thetwisters will be turned one-half of arevolution. After two revolutionsto the left of the twisters and spoolcarriers at this time, and whilethe studs A A are passing from the right to the left of the plate 13,the disks are at rest during this time, and the sliding plate K isactuated by the spur-wheel M and the intermediate mechanism.

The inclined slots k, as they pass over the twisting-disks, engage thewires that may be in the notches of the same, carry them over and placethem in the notches of the adjacent or intermediate twisting-disk whileyet the disks are at rest, and hold the wires in the disks by the edgesof the holes it until the twisting-disks revolve, when they are retainedby the twisting of the wires.

The twisting is accomplished by placing the wires which are to betwisted together in opposite notches of the same twisting-disk.

As before stated, the wires are first placed in the notches in theopposite sides of each alternate twisting-disk. The series of meshes as,Fig. 1, are formed by the same disks that the meshes x are formed by.

The twisting of the meshes or being accomplished, the disks being, asbefore stated, at rest, the inclined slots lc transfer the wires to tothe alternate or intermediate twisting-disks directly beneath thetwisted portion of the wires at 11 and which twisted the same, and thewire w is, by the same means, transferred to the twisting-disk which hasthe righthand edge-wire, G, in its eye, and by this disk is carriedtwice around the G wire, forming the edge and half-mesh 20 WVhen thetwisting has been accomplished, the wires are again returned by theinclined slots it to the disk from which theywere taken, the sameinclined slot carrying the same wire from one twister to the sametwister and the same notch from which it was taken. From this it appearsthat when the machine is in operation one-half of the twisting-disks areidle-running, but not forming meshes-onehalf of the time, while theothers are working to form meshes.

The draw-feed is taken up at the same time that the wires are beingtransferred from one disk to the other by the transferplate, and thelength of the meshes is regulated at will by the feed-lever devices, soas to form a long diamond-shaped or square mesh.

The movable pulleys on the shaft 9 are moved to the left as the carriersare turning to the left, and to the right as they are turned to theright, so as to lessen the latitudinal motion of the carriers in passingaround the wires.
